It's a no-prep, self-checking review game that runs in any browser — no apps, no logins, no printing. Just send the link and let them race the clock.

The mission

• Work through a series of animated rounding challenges.
• Each correct answer reveals a code that unlocks the next room.
• Wrong answers won't open the lock, so the room checks itself.
• Crack the final code to escape and win.
